Pushover Analysis of a Reinforced Concrete High Rise Frame Building with Aerated Autoclave Concrete Brick Infill and its Behavior with and without Shear Wall

Abstract

In this research study, the effect of adopting Aerated Autoclave Concrete (AAC) bricks infill in high-rise buildings has been studied, with focus on its influence on the building during an Earthquake. The building models of two different heights are chosen. This paper presents the static non-linear analysis (Pushover Analysis) of high-rise concrete building using Aerated Autoclave concrete (AAC) blocks as brick infill and its behavior with and without a shear wall. By Performing pushover analysis, it gives the performance level of the building, plastic hinges and pushover curves. The static non-linear analysis provides a greater perceptive and more precise Structural seismic reliability and also the failure elements of the structure.
